When using auto accompaniment, my Ketron Audya does like any “ slips” of the fingered, meaning you need to play very accurate for best results. My Kong Havian and Yamaha 950 are much more forgiving, which I prefer, because nobody is perfect!
Its not so much the auto accompaniment...
But more the advanced super natural voices of the Roland, that are much harder and take more time to get good results then Yamaha’s sa2 voices ...
